I am having issues getting the Technical component of a second pathology procedure paid. In our dermatology clinic our provider preps and reads our pathology but in some cases he needs to send out the slide for consult. I am having the issue of the second slide prep being denied. I bill the first line with the 88305 and no modifiers since we prepped and read the slide. The second line I bill with the 91 and TC modifier which was suggested to me by another coder to indicate it is a separate slide that we only performed the technical component for. I am being told by the payer this second prep is "included in the global fee" and is denied. I am getting nowhere with this and any suggestions on how to bill this would be appreciated.
